OF RAIIVVAY, NEW JERSEY, A COR- SPECIFICATION forming part of Letters Patent No. 714,857, dated December 2, 1 Application filed June 27, 1902. Serial No. 113,421. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV A. BRACHHAU- SEN, a citizen of the United States, residing at Rahway, Union county, State of New Jersey, have invented certain new and useful Improvements in Note-Sheet-Lifting Mechanisms for Music-Boxes, of which the following is a specification.-

My invention relates to music-boxes, and particularly to that class in which a plurality of note-sheets are supported on a carriage by means of which the sheets may be brought successively to the playing position. My present invention has especial reference to the mechanism which takes the sheets singly from the carriage and raises them into contact with the mechanism employed for rotating the sheets.

The object of the invention is to provide a mechanism of this class which will operate positively and which particularly will not be liable to become loose and untrustworthy by continued use.

The accompanying drawings show a specific embodiment of my invention, while the appended claims indicate the scope of my invention.

Figure l is an elevation of a portion of a music-box, showing my improvements applied thereto, with parts in section. Fig. 2 is a front elevation of the lifting member and the adjacent parts, and Fig. 3 shows the same parts as seen from the inside.

The frame 1 of the machine is provided with brackets 2, supporting tracks 3, upon which are adapted to run rollers 4 on the carriage 6, which is of any suitable construction and which is represented as provided with a number of rods 8, between which the note-sheets are adapted to be received. The mechanism for moving this carriage forms no part of my present invention and is there fore not shown. It will be understood, how-' ever, that the carriage is so moved that when at rest it will hold one of the tune-sheets in proper position to be engaged by the lifting mechanism to be described presently and to be carried by said lifting mechanism into operative relation with the parts which hold and rotate the note-sheet. These holding parts are indicated generically by the letter H in the drawings and may be of any approved construction.

51 indicates the spring-drum, which is employed to rotate the note-sheet in any suitable manner and also to effect the proper timing of the entire mechanism. This drum and its connections form no part of my present invention, except as hereinafter stated. Upon the drum is provided a cam 49, with which is engaged a roller 48 on lever 46, fulcrumed at 47 upon the frame of the machine. Thelever 46 is connected at 45 with a link 45, extending to a central crank 44 upon a rock shaft 43. This shaft is provided at both ends with crank-arms 42, the free ends of which have pivotal connections at 42 with links 41. The upper end of each link 41 is pivotally connected, as at 41 with a slide 39, arranged to move on a vertical track 40, arranged to coincide with a plane between two adjacent arms or holders 8 and also to practically coincide with the plane in which the tunedisk is held during its rotation. The slides 39 are preferably provided with antifrictionrollers 39, en gaging'the tracks 40 at opposite sides. Each slide has inwardly-projecting arms 38, provided at their free ends with shoes 38, which are adapted to engage the lower edge of a tune-sheet supported on the carriage 6. In order to secure a steady movement of the slides 39 at the beginning of their upward stroke, I may arrange at each side of the arms 38 vertical guides 37, projected from a bracket 36, secured to the track 40. Fig. 1 shows the cam 49 in the position of rest, when the shoes 38 are below the notesheet. As the drum 51 rotates in the direction indicated by the arrow the outer end of the lever 46 is raised, and through the connections described the shoes 38 are lifted so as to engage the note-sheet with which they register and to then carry such note-sheet upward to the playing position. It will be observed that the motion is a positive one and that the liability of inaccurate operation due to the stretching of parts is minimized.

What I claimas new, and desire to secure by Letters Patent, is-

1. In a music-box, the combination with a tracks, means for operating said slides, and arms projecting inwardly from the slides and arranged to pass between the said guides, the [5 said arms being provided with shoes arranged to engage the note-sheets on the carriage.

In testimony whereof I have signed my name to this specification in the presence of traveling carriage, of tracks extending transversely of the carriage-path, slides arranged to travel on said tracks, arms projected in- Wardly from the slides and adapted to engage 5 the note-sheets held on the carriage, and guides between which said arms are arranged to move.

2. In a music-box, the combination of a two subscribing witnesses.
